If you should mean me, which good news do you expect from my side?
I am not able to create the code of an NVMe Option ROM module. The structure and the content of Option ROM and EFI "Driver" modules are completely different.

Here is an ASRock mainboard with support for NVMe in BIOS version 1.80: LINK
And here a user assumes, that RST OROM and EFI driver module 13.1 or above is enough to get NVMe working: LINK

From v13.2.0.1016 release notes & OEM documentation (Note 5):

So this means, that RST support for NVMe devices way delayed to version 13.7.
But the ASRock X99 Extreme3 hast NVMe support with RST 13.1 and 13.2 modules in BIOS.
Conflicting information OR RST support and general support are two totally different things...

Is the OEM documentation for RST 13.5 and 14.0 available online?
Maybe some documentation for RSTe 4.1?

As CodeRush said at post #3, adding NVMe support is not just about the RST firmware & driver. What OEMs mean is probably that the BIOS is now NVMe ready. When Intel decides to release an official NVMe RST firmware it's a completely different story.

Back in January I had done a small search for RST packages (firmware + documentation) but at the time I hadn't found anything after 13.0 and RSTe 3.0. Today (after 3 months) I added 13.2 OEM documentation. Source is MSI.

NVMe will be the successor of the AHCI standard and I doubt, that Intel will ever add NVMe support into their Intel RST/RSTe RAID ROM/EFI modules.
Furthermore I am not sure, whether we will ever get our hands on an Intel RST driver v13.7.

The latest BIOSes for my ASRock Z97 Extreme6 do support NVMe as well, but by completely separate NVMe modules (look >here<), which have nothing to do with the Intel RAID ROM/EFI modules.

I can't download those NVMe modules. I get a 0 Byte file...

I just tested it without any issue. The downloaded unzipped NVMe BIOS files have a size of 11 KB resp. 19 KB.

I am willing to try a modded BIOS.
I'll buy an Intel SSD 750 400GB.
You guys mod the hell out of my ASRock X79 Extreme4 and I test it.
Does this sound good to you?

EDIT: found THIS. At least ASUS talks about backporting NVMe to X79.
Maybe other companies will do the same, if ASUS succeeds...

No, not really.
You obviously overestimate the NVMe support options of your X79 mainboard and our BIOS modding abilities.

OK, then lets see what ASUS and maybe other manufaturers will do about this.

EDIT: Let me ask one last question: If ASUS deliveres a working backport for X79 systems,
would the modding community work on porting this to other manufacturers like MSI or Gigabyte?

#28 RE:[Discussions] NVMe Support by mr_nuub 15.04.2015 09:15

Guys, check this out!
ASUS had success on porting NVMe to Z87 and X79!
They now started a poll - let's vote!

#29 RE:[Discussions] NVMe Support by Jest 15.04.2015 09:42

Why would they add support to x79 and not to Z77, which is newer and more common?

Read the page I posted. They tested it with X79, Z77 and Z87.
They got good results on X79 and Z87, but they didn't post the reults for the Z77 chipset.

I want NVMe support for the X79 platform, because it's the "Enthusiast" platform.
It has 40 (!) PCIe lanes, so you can use 2 graphics cards AND the NVMe SSD.

Z77 is the performance consumer stuff. It has only 16 PCIe lanes.
So you have to cut down bandwidth for the graphics card (bad for GPGPU) or
use the integrated GPU if you want to use a NVMe SSD
(depends on the number of PCIe slots of your mainboard).

PS: The Z87 platform has only 16 PCIe lanes, just like Z77.
Z77/Z87 - I couldn't care less...
Nice to have, but not needed anyways...

EDIT: We are talking about CPU PCIe lanes.
The chipset only supports PCIe 2.0 x1 lanes and are completely useless for NVMe.
